DESCRIPTION OF THE BACKGROUND

WO 94/07492 discloses 4-hydrazinoquinolines and 4-hydrazonoquinolines which are pharmaceutically active.

While 4-quinolinehydrazines are disclosed in the literature, a fungicidal action of these compounds is not reported (cf.: Ann. Chim.(Rome), 46(1956)1050; J. Chem. Soc., 1930, 1999; J. Chem. Soc., 1938, 1083; Yakugaku Zasshi, 65(1945)Ed. B, 431; Farmaco, Ed. Sci., 30 (1975) 965), J. Med. Chem., 12 (1969) 801.

Various phenylazoquinolines are also described in the literature (cf. J. Heterocyclic Chem.; 21 (1984) 501; Ann. Chim.(Rome), 46(1956)1050; J. Chem. Soc; 1084, 1938).

Attl. Accad. Sci. Siena Fisiocrit. (1976) 8, 43-57 reports 4-hydrazonoquinolines which have a microbicidal action. However, these compounds are not reported as having a fungicidal action against plant pathogens.

SUMMARY OF THE INVENTION

It was an object of the present invention to provide quinoline derivatives which have a fungicidal action.

We have found that this object is achieved by compounds of the formula I, which have a good fungicidal activity against plant pathogens.

DETAILED DESCRIPTION OF THE INVENTION

The compounds of the present invention can be prepared by applying known syntheses. The starting compounds can be obtained by known methods.

The compounds of the general formula I are obtained by subjecting the 4-chloroquinolines of the formula II to a condensation reaction with hydrazines of the formula III. ##STR3##

Those quinolines II which are not already known can be obtained by known methods (Tetrahedron 41 (1985) 3033-36, Organic. Syntheses, Col. Vol.3,272 (1955), EP 497371, U.S. Pat. No. 5,240,940).

Those hydrazines III which are not already known can also be obtained by known methods (cf. Houben-Weyl, Volume 10/2, pages 1 to 71 and 169-409, especially 396-399 and 402-405).

The compounds of the general formula I are obtained by subjecting the 4-chloroquinolines II to a condensation reaction with hydrazines of the formula III.

The 4-chloroquinolines II are preferably reacted with the hydrazines in question at elevated temperatures in a suitable diluent. Suitable diluents are inert organic solvents, such as aliphatic hydrocarbons, eg. petroleum ether, aromatic hydrocarbons, eg. toluene or o-, m- or p-xylene, or else alcohols, eg. n-, i- or t-butanol.

The invention also encompasses the salts of the compounds I, in particular the salts of mineral acids or Lewis acids. The type of the salt is normally not critical. Preferred for the purposes of the invention are those salts which do not damage the plants, areas, materials or spaces to be kept free from harmful fungi and which do not adversely affect the activity of the compounds I.

The salts of the compounds I are accessible in a manner known per se, for example by reacting the relevant quinolines I with acids in water or an inert organic solvent at from -80° to 120°, preferably 0° to 60° C.

The invention also encompasses the N-oxides of the compounds I. They can be prepared by methods known from the literature (see, for example, Ann. Chim. Rome; 46(1956)1050).

Compounds Ia where R⁷, R⁸ are a bond can be prepared by methods known from the literature (see Houben-Weyl; Volume 10/3, pages 226-423), for example by coupling aromatic diazonium compounds (p. 226-311), by means of condensation reactions (p. 332-355) or by dehydrating the compounds of the general formula Ib where R⁷ and R⁸ are hydrogen (p. 377). ##STR4##

Suitable oxidants are inorganic and organic compounds, eg. peroxides, hypohalites, nitrous acid, nitric acid, metal salts, eg. Fe(III) salts, Cu(II) salts, Pb(IV) salts, but also oxygen or air.

Examples of suitable diluents are water, organic and inorganic acids, eg. glacial acetic acid, sulfuric acid or nitric acid; alcohols, eg. methanol or ethanol; halogenated hydrocarbons, aromatic hydrocarbons or else dimethylformamide.

The reaction temperature is generally from 0° to the boiling point of the solvent in question.

The novel compounds of the formula I are suitable as fungicides.

The novel compounds, or the compositions comprising them, can be employed for example in the form of ready-to-spray solutions, powders, suspensions, also highly concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading or granules or by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend on the intended aims; in any case, they should guarantee the finest possible distribution of the active ingredients according to the invention.

Normally, the plants are sprayed or dusted with the active ingredients, or the seeds of the plants are treated with the active ingredients.

The formulations are prepared in a known manner, eg. by extending the active ingredient with solvents and/or carriers, if desired using emulsifiers and dispersants, it also being possible to use other organic solvents and auxiliary solvents if water is used as the diluent. Auxiliaries which are suitable are essentially: solvents such as aromatics (eg. xylene), chlorinated aromatics (eg. chlorobenzenes), paraffins (eg. mineral oil fractions), alcohols (eg. methanol, butanol), ketones (eg. cyclohexanone), amines (eg. ethanolamine, dimethylformamide) and water; carriers such as ground natural minerals (eg. kaolins, clays, talc, chalk) and ground synthetic minerals (eg. highly-disperse silica, silicates); emulsifiers, such as non-ionic and anionic emulsifiers (eg. polyoxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates) and dispersants such as lignosulfite waste liquors and methylcellulose.

Suitable surfactants are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, eg. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl- and alkylarylsulfonates, alkyl, lauryl ether and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols and of fatty alcohol glycol ethers, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene, or of the naphthalenesulfonic acids, with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated iso-octyl-, octyl- or nonylphenol, alkylphenol polyglycol ethers, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene alkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignosulfite waste liquors or methylcellulose.

Powders, materials for spreading and dusts can be prepared by mixing or grinding the active ingredients together with a solid carrier.

Granules, eg. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers. Solid carriers are mineral earths such as silica gel, silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powder or other solid carriers.

Examples of such preparations are:

I. a solution of 90 parts by weight of a compound I according to the invention and 10 parts by weight of N-methyl-2-pyrrolidone, which is suitable for use in the form of microdrops;

II. a mixture of 10 parts by weight of a compound I according to the invention, 70 parts by weight of xylene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene oxide to 1 mol of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate, 5 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil; a dispersion is obtained by finely distributing the solution in water;

III. an aqueous dispersion of 10 parts by weight of a compound I according to the invention, 40 parts by weight of cyclohexanone, 30 parts by weight of iso-butanol, 20 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil;

IV. an aqueous dispersion of 10 parts by weight of a compound I according to the invention, 25 parts by weight of cyclohexanone, 55 parts by weight of a mineral oil fraction of boiling point 210 to 280° C. and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil;

V. a mixture, ground in a hammer mill, of 80 parts by weight of a preferably solid compound I according to the invention, 3 parts by weight of sodium di-iso-butylnaphthalene-α-sulfonate, 10 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liquor and 7 parts by weight of pulverulent silica gel; a spray mixture is obtained by finely distributing the mixture in water;

VI. an intimate mixture of 3 parts by weight of a compound I according to the invention and 97 parts by weight of finely divided kaolin; this dust comprises 3% by weight of active ingredient;

VII. an intimate mixture of 30 parts by weight of a compound I according to the invention, 62 parts by weight of pulverulent silica gel and 8 parts by weight of paraffin oil which has been sprayed onto the surface of this silica gel; this preparation imparts good adherence properties to the active ingredient;

VIII. a stable aqueous dispersion of 40 parts by weight of a compound I according to the invention, 10 parts by weight of the sodium salt of a phenolsulfonic acid/urea/formaldehyde condensate, 2 parts by weight of silica gel and 48 parts by weight of water, and this dispersion can be diluted further;

IX. a stable oily dispersion of 20 parts by weight of a compound I according to the invention, 2 parts by weight of calcium dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 20 parts by weight of the sodium salt of a phenolsulfonic acid/urea/formaldehyde condensate and 50 parts by weight of a paraffinic mineral oil.

The novel compounds are distinguished by an outstanding efficacy against a broad spectrum of phytopathogenic fungi, in particular from the classes of the Deuteromycetes, Ascomycetes, Phycomycetes and Basidiomycetes. Some of them act systemically and can be employed as foliar- and soil-acting fungicides.

They are especially important for controlling a large number of fungi in a variety of crop plants such as wheat, rye, barley, oats, rice, maize, lawns, cotton, soya, coffee, sugar cane, grapevines, fruit species, ornamentals and vegetable species such as cucumbers, beans and cucurbits, and on the seeds of these plants.

The compounds are applied by treating the fungi, or the seeds, plants, materials or the soil to be protected against fungal infection, with a fungicidally active amount of the active ingredient.

Application is effected before or after infection of the materials, plants or seeds with the fungi.

The novel compounds are specifically suitable for controlling the following plant diseases:

Erysiphe graminis (powdery mildew) in cereals, Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits, Podosphaera leucotricha in apples, Uncinula necator in grapevines, Puccinia species in cereals, Rhizoctonia species in cotton and lawns, Ustilago species in cereals and sugar cane, Venturia inaequalis (scab) in apples, Helminthosporium species in cereals, Septoria nodorum in wheat, Botrytis cinerea (gray mold) in strawberries, grapevines, ornamentals and vegetables, Cercospora arachidicola in groundnuts, Pseudocercosporella herpotrichoides in wheat and barley, Pyricularia oryzae in rice, Phytophthora infestans in potatoes and tomatoes, Fusarium and Verticillium species in various plants, Plasmopara viticola in grapevines and Alternaria species in vegetables and fruit.

The novel compounds can also be employed in the protection of materials (protection of wood), eg. against Paecilomyces variotii.

In general, the fungicidal compositions comprise from 0.1 to 95, preferably from 0.5 to 90, % by weight of active ingredient.

Depending on the nature of the desired effect, the rates of application are from 0.025 to 2, preferably 0.1 to 1 kg, of active ingredient per ha.

Activity against powdery mildew of wheat

Leaves of wheat seedlings cv. "Fruhgold" which had been grown in pots were sprayed with an aqueous spray mixture comprising 80% of active ingredient and 20% of emulsifier in the dry matter and, 24 hours after the spray coating had dried, dusted with oidia (spores) of powdery mildew of wheat (Erysiphe graminis var. tritici). The test plants were subseqently placed in the greenhouse at from 20 to 22° C. and a relative atmospheric humidity of from 75 to 80%. After 7 days, the extent of mildew development was determined.

Scoring:

The infected leaf area is indicated as a percentage.
